X-NUCLEO-LED16A1

扩展板, LED1642GW 16通道LED驱动器, 用于STM32 Nucleo

The from STMicroelectronics is a 16 channel LED driver expansion board based on LED1642GW for STM32 Nucleo. Multiple drivers can also be cascaded by coupling X-NUCLEO-LED16A1 expansion boards. Depending upon the end application, RGB or single colour LEDs can be connected to the board. Separate brightness control is possible for each channel. It is compatible with the STM32 Nucleo board family and equipped the Arduino UNO R3 connector layout.
